Guessed, thank you for fast response!

Macropod,

many thanks, the code works as expected except these few points:

1) If there is an inline image OR a complicated field (from a reference software) I get

Run-time error '5610': The Find What text for a Find All Word Forms search can only contain alphabetic letters.

I guess the 'StrFnd' value should be "flattened" to pure text and any images ignored. How to do that?

2) How to avoid highlighting of the spaces after found duplicates?

3) How to add greek/mathematic symbols to the exclusion list?

4) I would like to have a possibility to apply the macros to the selection or to the complete document if there is no selection. Is it possible too?
